    I happened to notice that the `cortex-a9` ISA does not have `mve`, which I care about today because I want to use `vsri`, which currently only resides in `arm.mve.vsri`. 

https://github.com/llvm/llvm-project/blob/b0662a7a7d6d7a4a5339b95d3a20a53390636716/llvm/include/llvm/IR/IntrinsicsARM.td#L1089-L1090

However, according to [this documentation](https://developer.arm.com/documentation/ddi0409/i/instruction-timing/cortex-a9-neon-mpe-instructions?lang=en), the `cortex-a9` has `vsri`, because it (also) exists within `neon mpe`. So LLVM should probably understand that and allow me to use that instruction on that machine unless there is a good reason not to.

Thank you!
